MOLD FOR TYPOGRAPHICAL MACHINES.

Specification of Letters Patent.

Patented @ct. 2%, 1915..

Application filed October 26, 1912. Serial n6. 727,852.

State of New York, have invented a new and useful Improvement in Moldsfor Typographical Machines, of which the following is a specification.

My invention has reference to typographical casting machines and aims atthe provision of a mold of improved construction to produce type bars ofspecial form for use in printing plain or ornamental designs aroundadvertisements, book pages, etc. It is now common practice to employ forthis purpose slugs or linotypes having a longitudinal border thereon,these slugs being arranged at right angles to one another and with theirends joined to form the corner of the border. In practice muchdifficulty is encountered in connecting and confining the endsaccurately and in such manner as to produce a close joint and anunbroken design. To obviate this objection, I propose to construct themold of such form that it will produce a printing bar or slug with itsopposite endsoffset to the other portion, as for instance turned up atright angles or in some other manner, and with the rule or borderthereon extending lengthwise and also turned at the corner, so that avertical slug bearing the same rule or border may be joined to theotherconveniently. This arrangement avoids the necessity for using separatecorner pieces and also the break or disconnection which frequentlyoccurs when it is attempted to joint mitered slugs.

In the accompanying drawing ll have shown my invention merely inpreferred form and by way of example, and I desire it to be understoodthat I do not limit myself to any specific form or embodiment except inso far as such limitations are specified in the claims. It is of coursemanifest that the printing design of the cast slug may be varied in anydesired manner.

Referring to the drawing: Figure. 1 is a view of a slug produced by myimproved mold, and showing its mode of'employment in connection withcooperating slugs; Fig. 2 is a detached view of a mold constructed inaccordance with my invention; Fig. 3 is a transverse section takensubstantially on the line 33 of Fig. 2: Fig. 4': is a similar sectiontaken on the line 4-4 of Fig. 2; and Fig. 5 shows a special form ofliner included in the mold construction.

The mold comprises as usual the cap portion C and the body portion D.Located between these parts is a liner E formed with a longitudinal slotor depression 6, constitutmg the mold cavity proper, and at the oppositeends of the depression 6, the liner is formed with transverse grooves 6communicating with the slot c. It will be noted I that the bottom wallof the depression 6 and the opposing face of the overlying cap portlon Care both plain or smooth throughout so that the slug cast in theintervening mold space will be solid or unrecessed in its side face.

Fig. 1 shows a slug A produced by my improved mold. The main or bodyportion of the slug is cast in the slot e and its offset ends A in thetransverse grooves 6 it being. noted that the grooves 6 projectlaterally from the slot 6 so that the offset portions A project beyondthe effective side face of the slug. The slug is formed with a printingprojection a which extends not only along the body of the slug but isalso turned at its ends to extend to the extremities of the offsetportions A in such manner that it meets and joins with similar printingprojections b on the vertical cooperating slugs B.

It will be noted that the recesses wherein the slug and its ofiset endsare cast are formed wholly in the liner E. This is advantageous since,by removing the liner and substituting others of the usual kind, themold may be employed for producing slugs of the ordinary construction.

.Having thus described my invention, its construction and mode ofoperation, what ll claim and desire to secure by Letters Patent of theUnited States, is as follows:

1. A linotype mold having a longitudinally extending slot wherein theslug is cast, the side walls of said slot being plain or straightthroughout so as to produce a solid .or unrecessed slug, and "one ofsaid walls being formed at one end of the mold slot with a transversegroove projecting laterally there'- from and communicating therewith andinto which the casting metal flows to produce on the slug an offsetportion which projects beyond its efiective side face and which isformed with a printing projection extending longitudinally along thebody of the slug and bent at the end.

2. A linotype mold having'a longitudinally extending slot wherein theslug is cast, the side walls of said slot being plain or straightthroughout so as to produce a solid or unrecessed slug, and one of saidwalls being formed at the opposite ends of the mold slot with transversegrooves projecting laterally therefrom and communicating therewith andinto which the casting metal flows to produce on the slug at itsopposite ends ofl'set portions projecting beyond its efiiective sideface and which is formed with a printing projection extendinglongitudinally along the body of the slug and bent at the end.

3. A mold element formed with a longitudinally extending slot ordepression passing transversely through the element from one edge to theother and with a transverse groove located at one end of the slot andcommunicating therewith.

4. A mold element formed with a longitu dinally extending slot ordepression passing transversely through the element from one edge to theother and with a transverse groove located at each end of the slot andcommunicating therewith.

5. A linotype mold comprising, in combi nation, top and bottom parts,and an intermediate mold element formed in its side face with alongitudinally extending depression passing transversely through theelement from one edge to the other constituting the mold slot proper,and further formed with a transverse groove located at one end of theslot and communicating therewith.

6. A mold having a longitudinally extending slot, the said slot beingformed wholly in one of the side walls of the mold, and the said wallbeing formed at one end of the slot with a transverse groovecommunicating therewith whereby a printing surface having elongated andbent-end portions may be cast.

In testimony whereof I hereunto set my hand this twenty third day ofOctober, 1912, in the presence of two attesting witnesses.
